I just installed a Sugino XD2 triple (46-36-324) on my 88 Schwinn Voyaguer with the original Shimano Deore MT-60 FD and 8 speed Ultegra bar end shifters (BS-64), The Sugino replaced the original Biopace triple.
Problem: With the shifter at maximum pull, the FD outer cage justs clears the chain (less than a fingernail of clearance) in 46T ring and 13T cog (smallest). The FD still can move outward, the shifter can not pull it anymore. The LBS tried many times to get the outer cage to clear the chain, so I think this is the best I will get.. Concern: Minimal Clearance. Over time, outer cage may contact chain in big ring - small cog. Background: I replaced the original DT shifters with the Bar ends in 2010, but kept the original FD (MT-60) and Biopace Triple (FCB-124). I had NO problem with imoving the shifter to trim the FD to eliminate chain noise in the big ring-small cog. I measured the distance from the SMALL ring to the LARGE ring on the Sugino XD2 and the FCB-124 Biopace. The Sugino is 1 mm wider, requiring more cable pull . Sugino: 18.5mm, Biopace 17..5mm The original Deore MT-60 FD has a very flat outer plate which slants inward. It seems to provide minimum clearance to the chain. The 88 Voyaguer came with a 50-44-26 Biopace and the FD really shifted the 50 to 44 very fast.. I replaced the 54 &44 rings with 48 and 38 biopace rings. Shifting was still good but not as fasr.. QUESTION FOR GROUP Is my problem the Suginoa is slightly wider and the MT-60 FD has minmal clearance with the flat plate outer cage???
